Stir together all seasonings in a small bowl and sprinkle over both sides of steaks. Cook on a lightly oiled grill over medium heat for about 5 minutes per side or until steaks are cooked to your liking. While steaks are cooking, grill jalapeņo peppers until well charred. Remove from grill and thinly slice. Drizzle with lime juice and sprinkle with salt; spoon over steaks.
